One of the most significant Intercom systems was designed for E.S.R.O. (European Space Research Organisation) for the satellite tracking bases.

The cooperation with E.S.R.O. began in 1970 and is today still active, with the expansion of the original system as well as the supply of new systems.

Each system enables connections between many operators located in different places around the world (Europe, America, Asia, Australia), in order to carry out telephone and intercom connections for the co-ordinated operation of satellite tracking.

The conference function provided was tested by NASA for the coordinated operations of space vehicles.
